Judd-Ofelt parameters for Nd3+ ions in a new series of (Mg, Ba)F2-based fluorophosphate glass (the MBBA system) are determined from the intensities of the integrated absorption bands of the Nd3+ ion in the MBBA system. The intensity parameters, Ω2, Ω6, and Ω4 for f-f transitions of Nd3+ ions are found to be -1.02, 10.82, and 4.27 (×1020 cm2), and 1.19, 3.95 and 3.11 in the MBBA/NdI and MBBA/NdII systems, respectively. The measured lifetime τf is 168 μs for the MBBA/NdI system, while the Judd-Ofelt analysis expects a radiative transition lifetime Arad for 4F3/2 to be 316 μs, resulting in a fluorescence quantum efficiency of 47%. The results are compared with those reported in the literature for other fluorophosphate glasses and show that 4F3/2 to 4I11/2 transition has the most potential for laser application with a peak fluorescence at 1056nm.
